| Is the diameter of a mil spec bigger tube bigger or smaller than a commercial. |

Quoted: So you are saying the diameter of a mil spec buffer tube is smaller than a commercial buffer tube where it goes up in the buttstock. What he is saying is that the threaded section notwithstanding, the tube the buttstock slides over is smaller in diameter on the mil-spec tube as opposed to the commercial tube, which is slightly larger in diameter. If you're thinking the commercial tube being larger in diameter is stronger, then you'd be wrong. True mil-spec tubes are made from 7075 aluminum as opposed to MOST commercial tubes being 6061 aluminum, which is weaker than 7075. Does this help? |

Quoted:
No my problem is I bought a DD furniture kit which is mil spec and the buttstock is to small for the buffer tube to slide into. My buffer tube is commercial. Your only choice is to either return the furniture kit or get a mil-spec buffer tube. Most manufacturers build their lower to mil spec but put a commercial tube on it for various reason. 99.9% chance that you'd fit a mil-spec tube on it fine. Any gun smith will be able to swap out the tube and stake it again for you. From a furniture perspective, you'd get more choices with a mil-spec tube. |
